Abstract

In accordance with the present invention, an improved collector means for a solar energy collector system having an absorber plate and a glazing panel spaced from at least one side of the absorber plate in which a cap means is coupled to and extends along one edge of the absorber plate and a depending leg extends over the complimentary edge of the glazing panel, the cap means having formed therein at least one air channel conforming in shape to the cross-sectional shape of the cap means and having air inlet means adjacent the bottom of a leg of the cap means in communication with the channel and an air outlet means adjacent the top of the cap means and in communication with the channel and adapted to permit currents of cooling air to pass therethrough from the inlet to the outlet, thereby maintaining said complimentary edge of the glazing panel relatively cool. In a preferred embodiment, the improved collector means is mounted edgewise adjacent the bottom of a parabolic trough-type reflector means and has a glazing panel on both exposed sides thereof. In accordance with a further embodiment of the present invention, the glazing panel is a flexible sheet material detachably coupled adjacent one edge of the absorber plate and the other end of a glazing material comprises a supply roll mounted adjacent the other edge of the absorber plate, whereby a fresh surface of glazing sheet material can be withdrawn from the roll and mounted parallel to the absorber plate as needed. Preferably, the roll of glazing sheet material is spring loaded so as to maintain the material taut, for example by a window shade-type roll means.
